Konica Minolta to Release the CS-3000HDR Spectroradiometer Capable of Measuring Ultra-low Luminance Areas up to the Highest Levels in the World

New Jersey (May 11, 2023) – Konica Minolta, Inc. (Konica Minolta) today announced that the company will release the CS-3000HDR spectroradiometer capable of measuring ultra-low luminance areas up to the highest levels in the world*1 as well as the CS-3000 and CS-2000Plus (the three models hereinafter collectively referred to as “the CS-3000 series”) in July 2023.

The CS-3000HDR is the succeeding model of the CS-2000A, which was highly evaluated for its outstanding measurement performance and was indispensable for developing and manufacturing various light-emitting devices, including high-definition displays. The CS-3000HDR is the flagship spectroradiometer model. While maintaining data compatibility with the CS-2000 series, the CS-3000HDR expanded the measurement range from low luminance to high luminance and achieved higher speed and automation of measurement.

The lineup of the CS-3000 series also includes the CS-3000, which is the standard model, and the CS-2000Plus, which is the cost-effective model, in addition to the CS-3000HDR, to contribute to the development of displays and lower process cost at manufacturing sites.

Value Proposition by the CS-3000 Series


1. Achieving accurate measurement with a high dynamic range from ultra-low luminance to high luminance

In response to measurement needs for displays, which continuously evolve to provide ever more vivid and higher-definition output, the CS-3000HDR achieves accurate measurement in a wide dynamic range down to 0.0001 cd/m2,*2 which is one-fifth the darkness measured by the CS-2000A for low luminance, and up to 10,000,000 cd/m2,*3 which is 20 times the brightness for high luminance. In addition to the LCD and OLED types commonly used today, it can measure standard values in high dynamic range (HDR) displays that use micro- or mini-LEDs.

2. Improving work efficiency by reducing the measurement time

In quality assurance and control of displays, reducing the measurement time in R&D and at production sites contributes greatly to improving work efficiency. The CS-3000HDR and CS-3000 feature the Super Fast mode, which performs calculations even faster than the conventional Fast mode. This Super Fast mode can significantly reduce the time, such as the gamma measurement time, which is one of the display calibration items, to 25% or less of the time needed with conventional equipment.*4

3. Fully automatic measurement system achieved by powered switching of the measurement angle

The CS-3000 series enables the user to select the measurement angle setting from 1°, 0.2°, and 0.1°. The CS-3000HDR and CS-3000 can be used in a fully automatic measurement system by powered switching using communication commands. This helps improve work efficiency at display development and production sites.

The minimum measurement diameter is φ0.5 mm, while the use of an optional close-up lens enables measurement of φ0.1 mm. This supports the measurement of light sources in tiny areas, such as instrument panels for vehicles and aircraft, as well as indicators for car audio systems, in addition to general displays.
